RELATED APPLICATION DATA

The present application claims priority to Australian Plan Breeders Rights Application Serial No. 2012/257 and which was filed on Nov. 28, 2012.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new, novel, and distinct variety of blueberry plant ‘Vaccinium Hybrid,’ and which has been denominated varietally, as ‘EB 8-21’, hereinafter.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of blueberry plant resulted from an ongoing development program of plant breeding. The purpose of this program is to improve the commercial quality of various plant varieties by creating and releasing promising selections of plants including blueberries. To this end, I have made both controlled and hybrid cross-pollinations each year in order to produce experimental plant populations from which improved progenies are evaluated and selected.

The blueberry plant ‘EB 8-21’ was originated by me and selected from a population of new plants growing on my farm, and which is located near Yanchep Springs, Western Australia. The new plant was derived from a controlled pollination, which was conducted using the seed parent ‘SB-1’, and the pollen parent ‘03-6’ during the 2005 growing season, on my farm which is located in Yanchep Springs, Yanchep Western Australia. The seed parent ‘SB-1’, and the pollen parent ‘03-6’ are both unpatented. The seed parent is principally characterized as to novelty by a semi-spreading growth habit; an early season of flowering; and which further produces fruit having a medium size for the species. On the other hand, the pollen parent is characterized by a spreading growth habit; an early season of flowering; and which further produces large fruit. Seed derived from the seed parent (‘SB-1’) [unpatented], produced approximately 500 plants. The first fruit from this first cross-pollination was studied during the 2007 growing season.

A subsequent assessment took place in 2008, and the new variety ‘EB 8-21’ showed particularly desirable character traits. Further commercial testing including vegetative propagation from cuttings taken from ‘EB 8-21’ occurred during the 2009 through 2012 growing seasons. The resulting progeny appeared true to the original plant. Subsequent evaluations has led the inventor to conclude that the new variety is novel and distinct. The present variety is characterized as to novelty by producing extra large sized fruit, and which further has a small, dry picking scar, very good fruit flavor, and an early flowering and fruit production dates.

The closest known variety to the new variety ‘EB 8-21’ is the “Sharpeblue” blueberry plant (unpatented), and which produces fruit which are mature for harvesting and shipment early to the middle of the season, and which further has a fruit size which is average as compared to other blueberry plants. Still further, the “Sharpeblue” blueberry plant has an intermediate growth habit and a fruit shape which is considered to be oblate. The new plant ‘EB 8-21’, in contrast, has a date of fruit harvesting which is considered to be very early in the season, and which additionally produces very large fruit, and has an upright growth habit which is in contrast to the closest known variety.

DETAILED DESCRIPTION

Referring more specifically to the botanical details of this new and distinct variety of blueberry plant, the following has been observed during the sixth fruiting season under the ecological conditions prevailing at the farm of the inventor, which is located in Yanchep Springs, Yanchep Western Australia.

-   Plant:     -   -   Plant vigor.—Strong to very strong. This is in contrast to             the closest known variety, that being the ‘Sharpeblue’             blueberry plant (unpatented) and which is the closest known             variety and which has a plant vigor characteristic which is             considered only average to strong in comparison to other             similar varieties.         -   Plant growth habit.—Generally — Considered upright. This is             in contrast to the growth habit which is expressed by the             closest known variety and which is considered to be average.         -   Color.—One Year Old Shoots — Considered green. This color is             not distinctive of the present variety and is similar to the             color as expressed by the closest known variety             ‘Sharpeblue’.         -   Internode length.—One Year Old Shoots — Considered medium             for the species. This characteristic is distinguishable from             the same growth characteristic as expressed by the closest             known variety and which is medium to long. -   Leaf:     -   -   Leaf length.—Considered average for the species. This is in             contrast to the closest known variety which has a leaf             length which is considered average to long.         -   Leaf width.—Considered average. This is in contrast to the             growth characteristic as expressed by the closest known             variety where the leaf width is considered average to broad.         -   Leaf length/width ratio.—Considered average. This is in             contrast to the closest known variety where the same             characteristic is considered average to large.         -   Leaf shape.—Generally — Ovate. This is similar to the same             growth characteristic as expressed by the ‘Sharpeblue’             blueberry plant.         -   Leaf color.—Dorsal Surface — Green. This is similar to the             growth characteristic as expressed by the closest known             variety.         -   Leaf color intensity.—Dorsal Surface — The present variety             has a medium to dark green color. This is in contrast to the             same growth characteristic as expressed by the closest known             variety where the same green coloration is considered light             to medium.         -   Leaf margin.—Generally — Considered Entire. This is similar             to the closest known variety. -   Flower:     -   -   Anthocyanin coloration.—Considered very weak for the             species. This is similar to the same growth characteristic             as expressed by the closest known variety.         -   Inflorescence length.—Considered average. This is similar to             the same growth characteristic as expressed by the closest             known variety.         -   Flower shape.—Corolla — Urceolate.         -   Corolla tube.—Size — Considered average. This is in contrast             to the closest known variety where the size of the corolla             tube is considered average to large.         -   Corolla tube coloration — anthocyanin.—Very weak to weak.             This is in contrast to the merely weak coloration of the             corolla tube as seen in the closest known variety.         -   Corolla tube ridges.—Present. These ridges are also seen in             the closest known variety. -   Fruit:     -   -   Fruit cluster density.—Considered dense. This is in contrast             to the closest known variety where the same growth             characteristic is seen as dense to very dense.         -   Unripe fruit.—Color Intensity — Considered average for the             species. This is in contrast to the growth characteristic as             expressed in the closest known variety where the unripe             fruit color is considered light to medium green.         -   Fruit size.—Generally — Considered very large for the             species. This is in contrast to the fruit size as expressed             by the closest known variety and where the fruit size is             considered merely average. The fruit shape when viewed in a             longitudinal section is considered oblate. This is similar             to the closest known variety.         -   Sepal position.—Considered semi-erect. This is in contrast             to the sepal position or attitude characteristics as             expressed by the closest known variety, that being, the             ‘Sharpeblue’ blueberry plant and where the attitude of the             sepals is considered to be merely erect.         -   Fruit sepal type.—Considered incurving. This is in contrast             to the same characteristic as expressed in the closest known             variety and which is considered to be straight.         -   Calyx diameter basin.—Considered average. This is in             contrast to the same characteristic expressed by the closest             known variety and which is considered small to medium.         -   Calyx basin/depth.—Considered average for the species. This             is very similar to the growth characteristic as expressed by             the closest known variety.         -   Fruit.—Bloom Intensity — Considered strong. This is similar             to what is seen in the closest known variety.         -   Skin color.—Dark blue. This color is similar to the color as             seen in the closest known variety.         -   Fruit firmness.—Generally speaking the present variety             produces firm, to very firm fruit. This is in contrast to             the soft to average firmness as typically experienced in the             fruit produced by the closest known variety.         -   Fruit sweetness.—Considered medium to high. This is in             contrast to the closest known variety where the fruit             sweetness is considered merely average.         -   Fruit acidity.—Generally — Low to medium. This is in             contrast to the closest known variety where fruit acidity is             considered merely average.         -   Fruiting portions of the plant.—Fruit may be found on one             year old and current seasons shoots. This is similar to the             same growth characteristics as expressed in the ‘Sharpeblue’             blueberry plant.         -   Time of vegetative bud burst.—Generally speaking, the             vegetative bud burst is considered to be very early in the             season. This time of bud burst is earlier than that observed             in the closest known variety.         -   Flowering time — one year old shoots.—Considered very early             in the season, and earlier in time than that as seen in the             closest known variety.         -   Flowering time on current year's shoots.—Considered very             early in the season, and earlier in time than that as seen             in the closest known variety.         -   Fruit ripening time on one year old shoots.—Considered very             early in the season for the species. This is in contrast to             the same growth characteristic as expressed by the closest             known variety ‘Sharpeblue’ blueberry plant, and where the             time of fruit ripening begins early to medium in the season.         -   Fruit ripening time on current year's shoots.—Considered             very early in the season and earlier in time than the same             growth characteristic as expressed by the closest known             variety ‘Sharpeblue’ blueberry plant.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. The present variety has not             been tested to expose or detect any susceptibilities or             resistances to any known plant and/or fruit diseases.

Although the new variety of blueberry plant possesses the described characteristics when grown under the ecological conditions prevailing near Yanchep Springs, Western Australia, it should be understood that the variations of the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning, pest control, frost, climatic variables and horticultural management are to be expected. 

Having thus described and illustrated my new variety of blueberry plant, what I claim is new and desire to secure by plant Letters Patent is:
 1. A distinct variety of blueberry plant, substantially as illustrated and described and which is characterized principally as to novelty by producing fruit which are mature for harvesting and shipment very early in the season, and which are further very large in size, and wherein further, the plant exhibits an upright growth pattern under the ecological conditions prevailing near Yanchep Springs, Western Australia.
